Description

  • The invention relates to an image processing system for motor vehicles according to the features of the preamble of claim 1.
  • Modern motor vehicles are increasingly with Assistance and security systems equipped. In particular, image processing systems, which camera image data of the environment or the interior of a vehicle Process gain increasing importance, the processed image data the driver or in-vehicle systems in whole or in part. When using the image processing in the motor vehicle, however, this has to meet a wide variety of requirements.
  • From the DE 198 52 631 A1 a system for traffic sign recognition is known in which in the image data recorded by a camera system, by the image processing unit those image components are to be identified, in which a traffic sign is displayed. Subsequent to the identification, the image processing unit extracts these image areas and displays them to the driver via a display unit for final assessment.
  • A complex image processing method, which evaluates the image data of a multi-camera system and brings to the display is from the DE 199 26 559 A1 known. In this case, a distance-resolved image data material is generated by the fusion of the image data of the preceding environment of a vehicle recorded from different viewing directions. Based on these data, the image processing unit estimates the distances to objects and determines their relative velocities.
  • An image processing system adapted to process the image data received from an infrared sensitive wavelength camera is disclosed in US Pat DE 101 24 005 A1 described. In this case, the image processing system identifies different areas in the image data using classification algorithms and superimposes them with textures that are familiar to a natural observer, depending on their class membership.
  • These exemplified, Be known from the prior art image processing systems realized by means of vehicle-specific control unit solutions. in this connection are the controllers in in terms of their electromechanical properties, in particular with regard to their temperature resistance and stability, on in the motor vehicle dominating and fluctuating too in certain circumstances laying out extreme operating conditions; so surrendered inside the vehicle, especially in strong sunlight Very high temperatures in summer. Also, the individual system components of the Control devices, especially with regard to customary quite long service life of a motor vehicle high demands in terms of longevity suffice. In particular, the aforementioned factors result in relatively high development and production costs for camera-based Assistance and security systems.
  • The object of the invention is a Image processing system for To create motor vehicles which without limitation in functionality and reliability has comparatively low development and production costs, by making lower demands on the electro-mechanical properties and the longevity of the system components can be made.
  • The task is performed by a device solved with the features of claim 1. Advantageous embodiments and further developments of the invention are described in the subclaims.
  • The novel image processing system for motor vehicles comprises a camera system ( 2 ), an image processing module ( 3 ) for processing the image data supplied by the camera system, as well as a display unit ( 4 ) for displaying the processed image data. Here, the image processing module consists of a data interface for receiving the image data generated by the camera system, a memory unit for storing an image processing program and a processor unit for processing the image data. In an innovative way, the image processing module and the display unit are located in a microcomputer ( 5 ), in particular a palmtop or personal digital assistant (PDA) or a mobile phone. The microcomputer is in this case designed so that it can be detachably attached in the passenger compartment of the motor vehicle, at a location visible to at least one of the passengers.
  • The integration of the image processing module ( 3 ) in the vehicle interior ( 1 ) ensures that it is not exposed to such extreme temperature fluctuations or extreme temperatures as is the case for the conventional integration of such units in a control unit in the engine compartment. This is because the passenger compartment ( 1 ) of motor vehicles when driving is usually cooled by air conditioning or targeted ventilation to room or at least outside temperature. In particular, by using a microcomputer ( 5 ) in the function as an in-vehicle image processing module and image display unit, it is further ensured that this does not remain in the parked state of the vehicle in this, but due to its other functionalities by the driver or other insas is carried along. The image processing module ( 3 ) thus usually does not remain in a parked in blazing sun motor vehicle.
  • In this way, the inventive attachment of the image processing module ( 3 ) as part of a microcomputer ( 5 ) in the interior ( 1 ) of the motor vehicle in a particularly advantageous manner, the requirements of its electromechanical properties. Of course, the installation of the microcomputer ( 5 ) In the interior of the motor vehicle and the effort to protect the image processing module from penetrating moisture and condensation moisture significantly reduced.
  • Characterized in that advantageously the image processing module ( 3 ) and the display ( 4 ) of the image processing device through the processor module and the display of a microcomputer ( 5 ), in particular a palmtop or personal digital assistant (PDA) or a mobile phone, the requirements for longevity of the system can be considerably reduced. While the functional life of conventional systems, in particular due to their high cost and the considerable cost of a replacement, as possible for the entire useful life of a motor vehicle (about 12 years) must be ensured, it is now common for owners of microcomputers, in comparison with the Useful life of a motor vehicle relatively short time (2 to 3 years) to exchange such microcomputer. Not only does the replacement or replacement significantly reduce the longevity requirements of an image processing system, but it also achieves, in a profitable manner, that the image processing system continually improves in its performance as each new generation of microcomputers greatly increases processor performance having. By replacing the microcomputer with a modern model variant, the user of the image processing system also receives an adaptation of its display device to a modern standard.
  • From the field of research and It is indeed the development of image processing systems for motor vehicles already known, flexibly configurable computer systems with associated display for Processing and display of image signals. in this connection However, these are complex, flexibly configurable development systems whose Computer system is often located in the trunk of the vehicle, and which over commercial PC keyboards are operated. Come to the visualization of the image data ordinary, mostly dashboard-mounted LCD PC displays are used. In the cases in which the development of the image processing software is already is in the advanced stage of development and thus not more processor power is needed, it is known this on laptops inside the vehicle, though arise due to the weight of the computer mechanical problems with the necessary vibration-free storage. That's why often passed over to it provisionally attach the laptops in the passenger seat or while driving on your lap or to hold in the hand. All these from the field of research and Development known arrangements provide as shown temporaries which is not for a use in the production vehicle own; but not at all are provided. The regular approach of the Professional world shows that following a successful trial period the image processing algorithm ultimately always in connection with a special ECU hardware is used. The transfer The image processing algorithm on a controller is for the average Professional not only because of the usual in this field Approaching procedure, but also results from his Knowledge about the awkwardness of the development systems and the low available standing space, which of different interest groups is claimed.
  • In contrast to the usual, in the novel, inventive image processing system now remains next to the necessary image display ( 4 ), also the image processing module ( 3 ) in the vehicle interior ( 1 ). In contrast to the known research and development systems, however, the components are reduced to the bare minimum in a single housing, a microcomputer ( 5 ), compact integrated. Due to the low weight of the microcomputer ( 5 ) is for its secure storage usually a mechanically simple mount sufficient.
  • By the invention, it is now no longer necessary to reserve a space for the integration of a fixed image display in the area of the dashboard, since the display part of the microcomputer ( 5 ), whose holder can be attached to any visible location. It is even conceivable that the user of the image processing system is left free at which point of the vehicle interior ( 1 ) he the microcomputer ( 5 ) wants to attach. It is also possible to provide several alternative holders, so that depending on the application, the Kleistcomputer can be positioned at different locations. For example, to display traffic signs for the driver, or to display environmental images for occupants on the vehicle rear seats. In a particularly profitable manner, it is conceivable not only to install several brackets distributed in the vehicle, but to use parallel multiple microcomputers with integrated image processing modules for a variety of applications. It is only necessary to ensure that each of the image processing modules ( 3 ) With the one or more camera systems via a communication link ( 6 ) is in contact.
  • The detachable integration of the image processing module ( 3 ) in the vehicle offers the further advantage that one and the same module can be used in several vehicles. Thus, by purchasing a single image processing module, a vehicle driver can use it by carrying the appropriately prepared microcomputer in several vehicles. For example, it also eliminates the need for each of the vehicles of their fleet with a special image processing system for vehicle rental companies. If unforeseen more systems than needed are needed, additional equipment can be procured and made available relatively quickly, since no time-consuming and expensive ECU installation is required.
  • By using a conventional microcomputer ( 5 ), which is increasingly popular among vehicle owners, thus results in a continuous increase in processor performance and image display quality during the usage time of the image processing system.
  • Especially in economic The invention offers the possibility of a simple way offering a wide range of different performance systems by: the for The image processing task optimized software on a variety of Microcomputers is offered. So it may be enough for some tasks be to use a monochrome display unit, or otherwise Systems though with limited functionality but inexpensive to offer on microcomputers of the last generation of devices.
  • In a particularly advantageous manner can the Use of the image processing system then improve when the microcomputer is provided with a data interface over which image processing programs can be read into its memory unit. This way you can on the System easily new and improved image processing algorithms and image display are installed. This is how the system adapts in a profitable way not only by the continuous replacement the system hardware (microcomputer), but also through regular adaptation the system software of increasing development and increasing Requirements.
  • In a particularly profitable way it is conceivable to the users of the image processing system in relation on purpose of use and state of development different image processing algorithms offer. In this way, another value creation opportunity for the Manufacturer of the image processing system opened. It is this possible the Bildverarbeitungsalgorithmik in the context of a software product on distribute a wide variety of storage media. It is also conceivable as a distribution channel, for example, to use the Internet and the Software products as a free or paid download on the web page of the manufacturer of the image processing system or the vehicle manufacturer whose vehicles for receiving such Systems are prepared to offer. The user of the novel Image processing system can thus do this by acquiring and the optimal use of these special computer program products adapt its requirements.
  • If the memory of the microcomputer it allows is it possible to use algorithmics for Various types of image processing to install in parallel. For example, algorithm for evaluating image data of a Infrared system, from image data of a multi-camera system or a special algorithm for pedestrian recognition in downtown scenarios. In general, the processor performance not all of these complex tasks are parallel enough in parallel to edit. In particular, therefore, the microcomputer in profitable manner via input means be provided, which allow a selection of respect to the circumstances most suitable processing algorithm or display modes select. This could best be done over one Menu navigation by means of the standard keyboard of the microcomputer.
  • The camera module associated with the image processing module and display unit located in the microcomputer can be permanently integrated in the vehicle and can be connected to it via an interface located in the holder of the microcomputer. In this case, it is conceivable to carry out the camera module in a separable manner from the wiring between the camera module and the microcomputer so that, if necessary, the camera module can be exchanged and thus adapted to further technical developments. In such a case, a motor vehicle can be inexpensively mass-produced with a cabling to which, if required, for example, if desired, the special equipment with an image processing system, a suitable camera can be mounted. On the other hand, the vehicle user is thereby also given the opportunity to use his own, already existing camera as a camera system for the image processing system. For this purpose, it lends itself in a profitable manner, to attach as universally as possible to a variety of common camera modules bracket in the vehicle. It is equally conceivable, however, not to further prefabricate the motor vehicle apart from a receptacle for the microcomputer and optionally a universal receptacle for the camera module. Often already on the market image acquisition system consisting of microcomputer and camera module with associated communication path (for example, connection line) offered. Such complete systems could be problem-free be releasably introduced in located in the vehicle brackets. If the software usually installed on such microcomputers, which is suitable for image acquisition, is replaced by complex image processing software, contrary to the original intended use of pure image acquisition (photography) or image transmission (image telephony), a flexibly applicable image processing system in the motor vehicle results.
  • The functionality of the new image processing system In particular, this can also be increased by the microcomputer is provided with an interface over which data to and from In-vehicle systems can be transferred. In such in-vehicle Systems are in particular driver assistance systems, which act in hazardous situations to regulate the driving dynamics can (For example: braking or avoiding obstacles or Warning the driver).
